var redball = new Array (); var redlen = redball.length; 　while (redlen<6) {var ball = Rannumber (1,33); 　var flag = true; 　　　for (Var j=0;j<redlen;j++) {if (Redball[j]==ball) {flag = false; 　　Break 　　} if (flag) {if (ball<10) {Redball.push ("0″+ball);" 　　}else{Redball.push (ball); } Redlen = Redball.length; } redball.sort (); var BlueBall = Rannumber (1,16); if (blueball<10) {blueball = "0″+blueball;} Alert (Redball.join (', ') + "|" + BlueBall);

Here is the Rannumber method, which returns a random integer between S and E.
